We examine conditions under which a semicomputable set in a computable metric space is computable. In particular, we focus on wedge of circles and prove that each semicomputable wedge of circles is computable.

[Purpose] This study developed a pelvic wedge and belt and investigated their effects on the selective activation of medial and lateral hamstring muscles during knee flexion. [Subjects and Methods] Nine adults were enrolled. The participants performed exercises without and with the pelvic wedge and belt, and the electromyographic activities of the medial and lateral hamstring muscles were recor...

In this proceedings a particular example from [KMPY] is presented: the construction of the level 2 Fock space of Uq(ŝl2). The generating ideal of the wedge relations is given and the wedge space defined. Normal ordering of wedges is defined in terms of the energy function. Normally ordered wedges form a base of the wedge space. The q-deformed Fock space is defined as the space of semi-infinite ...

This study proposes an algorithm for selecting beam weight, wedge angle, and wedge orientation for three-dimensional radiation therapy treatment planning. According to dose gradient analysis, the necessary and sufficient condition for achieving a homogeneous dose over the target volume is that the total vector sum of the dose gradients of all beams be zero everywhere in the target volume. This ...

Three-dimensional L4-L5 finite element (FE) models of three disc heights (9.5mm, 11.5mm, and 13.5mm) and three disc wedge angles (5o, 8 o, and 10 o) were developed to investigate their effect on L4-L5 lumbar motion segment under pure axial compressive loading. The FE predictions indicated that the axial disc displacement and the posterior disc bulge increased greatly with an increase in the ave...

A numerical model of the medial open wedge tibial osteotomy based on the finite element method was developed. Two plate positions were tested numerically. In a configuration, (a), the plate was fixed in a medial position and (b) in an anteromedial position. The simulation took into account soft tissues preload, muscular tonus and maximal gait load.The maximal stresses observed in the four struc...

Wedge-shaped defects are frequently observed on the cervical region of the human tooth. Previously, most studies explained that improper tooth-brushing causes such defects. However, recent clinical observation suggested that the repeated stress due to occlusal force may induce the formation of these wedge-shaped defects. In this study, therefore, two-dimensional human tooth models are considere...

A varus-producing distal femoral osteotomy (DFO) is an effective technique for the treatment of lateral patellar instability (LPI) in patients with concomitant moderate to severe valgus malalignment. Patellar maltracking and subluxation are corrected via neutralization of some of the laterally directed forces on the patella due to the valgus deformity. This can be accomplished with a distal fem...

A laparoscopic wedge resection for a submucosal tumor, which is close to the gastroesophageal junction, is technically challenging. This can be a dilemma to both patients and surgeons when the tumor margin involves the gastroesophageal junction because a wedge resection in this situation might result in a deformity of the gastroesophageal junction or an injury to the lower esophageal sphincter,...

The thermal structure of a generic subduction zone is investigated to elucidate the source region of subduction zone volcanics. The steady state thermal field is evaluated for a model subduction zone where the plates are prescribed by kinematic boundary conditions, such that the subducting slab induces a flow in the mantle wedge. The resulting model suggests that the oceanic crust of the downgo...
